A function may return a pointer, but the programmer must ensure that the pointer a. still points to a valid object after the function ends b. still points to a valid object after the function ends c. was received as a parameter by the function d. has not previously been returned by another function
Answers
A function may return a pointer, but the programmer must ensure that the pointer is: a) still points to a valid object after the function ends.
In C programming language, a function can return a pointer to its calling function. In this case, the programmer must ensure that the pointer still points to a valid object after the function ends. As a result, the answer to the question is a. A pointer is a variable that stores the memory location of another variable. If the memory location is no longer valid, the pointer would be pointing to something that no longer exists.
As a result, if a pointer to an object is passed to a function and the function modifies the object, the programmer must ensure that the memory address being pointed to by the pointer remains valid. To ensure that the pointer remains valid, the programmer can use techniques such as dynamic memory allocation or static memory allocation. This ensures that the memory being pointed to by the pointer is still valid after the function has finished executing. Thus, the the answer is a) still points to a valid object after the function ends.

A function can return a pointer, but the programmer should ensure that the pointer still points to a valid object after the function ends. When we declare a function that returns a pointer, it is usually to a new object, and the pointer variable is just a reference to that object.
When the function returns, the variable referencing the new object will cease to exist, so we must ensure that the object itself is still accessible to the rest of the code.Explanation:When we use a function to allocate memory, for example, we have to be cautious to ensure that the memory is still allocated when the function returns. This can be accomplished by creating the object within the function, or by making certain that the function does not release the memory until after the pointer has been utilized or returned.It is also possible that the pointer has been passed to the function as a parameter, in which case the programmer does not need to worry about the pointer becoming invalid once the function terminates. Finally, if the pointer has been returned by another function, we must ensure that it has not already been freed before the pointer is utilized by another function.The answer is (a) still points to a valid object after the function ends.

Answers
Since we only support 32-word searches, "velocity" and any subsequent terms were not taken into account.
When an object rotates or circles around an axis, its angular velocity is the rate at which the angle between the two bodies changes. The angle that is made by a line on one body and a line on the other in the illustration represents this displacement.
A Ferris wheel, a race car driving in circles, and a roulette ball on a wheel are a few examples of angular velocity. The object's angular velocity also serves as a representation of the object's angular displacement with respect to time.
As a vector number that indicates an object's angular speed or rotational speed as well as the axis around which it is spinning, angular velocity is defined as the rate of change of angular displacement.

Air at a temperature of 150C passes through a heat exchanger at a velocity of 30 m/s where its temperature is raised to 8000C. It then enters a turbine with the same velocity of 30 m/s and expands until the temperature falls to 6500C. On leaving the turbine, the air is taken at a velocity of 60 m/s to a nozzle where it expands until the temperature falls to 5000C. If the air flow rate is 2 kg/s, calculate the following.
(i) Rate of heat transfer to the air in the heat exchanger,
(ii) Power output from the turbine assuming no heat loss, and
(iii) Velocity at exit from the nozzle, assuming no heat loss.
Take the enthalpy of air as h =cpt, where cp is the specific heat equal to 1. 005kJ/kg K and t is the temperature.
Answers
The power output from turbine assuming no heat loss and the velocity at exit from nozzle where Enthalphy h CpT i.e Cp specific heat = 1.005KJ/KgK.
What is meant by velocity?
Velocity is the direction speed of an item in motion as a measure of the rate at which its location is changing as seen from a certain point of view and as measured by a specific unit of time.A particle or object's movement with respect to time is expressed vectorially as velocity.As an alternative, the velocity magnitude can be expressed in centimetres per second (cm/s).Simply said, velocity is the rate of motion of an object in a specific direction. Using an automobile driving north on a highway as an example, or a rocket after it has launched, as an example of speed.The rate of flow of heat transfer to air exchanger i.e
\(w(h1+v^{2} 1/2+Z1g)+Q_{1-2} =w(h2+v2^{2} /2+Z1g)W_{1-2}\)
\(Wh_{1} +Q_{1-2} =Wh_{2}\)
\(Q_{1-2} =w(h_{1} -h_{2} )\)
\(Q_{1-2} =w_{cp} (t_{2} -t_{3} )\)
\(Q_{1-2}\) = 2xl.005(8000-150)
\(Q_{1-2}\) = 1577.8kgj/s
Velocity at exit from the nozzle, assuming no heat loss.
Given t₁ = 150°C, t₂ = 8000°c
V₁ = 30m/s, V₂ = 30m/s
t₃ = 6500°C , V₃ = 60m/s
\(W(v_{2} )^{2} /2+h_{2} )=Wh_{3} + (v3)^{2} /2+Wt\)
\((v2^{2}) -(v3^{2}) /2=(h2-h3)=Wt/w\)
\((30^{2} -60^{2} )x10^{-3} /2+(1.005)(8000-6500)=Wt/w\)
Wt = 1.506.15xw
Wt = 1506.15x2 = 3012.3kW
the enthalpy of air as h =cpt, where cp is the specific heat equal to 1. 005kJ/kg K and t is the temperature is 3012.3kW

Static Friction and Kinetic Friction
Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.
There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.
Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.
Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

Determine the component Ax of the support reactions of the fixed support A on the cantilever beam.
Answers
The component Ax of the support reactions of the fixed support A on the cantilever beam is [insert numerical value] (units).
In order to determine the component Ax of the support reactions at support A on the cantilever beam, we need to consider the equilibrium of forces acting on the beam. Since the support at A is fixed, it can provide both vertical and horizontal reactions.
For the vertical equilibrium, we can consider the sum of vertical forces acting on the beam. In this case, there are likely external loads acting on the beam, such as point loads or distributed loads. By summing these vertical forces and equating them to zero, we can determine the vertical component of the support reaction at A.
For the horizontal equilibrium, we need to consider the absence of any horizontal movement at support A. This implies that the horizontal component of the support reaction at A must balance out any external horizontal forces acting on the beam.
To determine the specific value of Ax, we would need additional information about the external loads and the geometry of the cantilever beam. This information would allow us to set up and solve equations based on the principles of equilibrium, such as the sum of forces and moments acting on the beam.
